plot_battery_ragone_diagram#

plot_battery_ragone_diagram(battery, save_figure=False, save_filename='Ragone_Plot', file_type='.png', width=11, height=7)[source]#

Creates a Ragone plot showing the relationship between specific power and specific energy of a battery.

Parameters:

  • battery (Battery) – RCAIDE battery object containing Ragone characteristics

  • save_figure (bool, optional) – Flag for saving the figure (default: False)

  • save_filename (str, optional) – Name of file for saved figure (default: “Ragone_Plot”)

  • file_type (str, optional) – File extension for saved figure (default: “.png”)

  • width (float, optional) – Figure width in inches (default: 11)

  • height (float, optional) – Figure height in inches (default: 7)

Returns:

fig – Figure handle containing the generated Ragone plot

Return type:

matplotlib.figure.Figure

Notes

The Ragone plot is a performance map showing the tradeoff between specific power and specific energy in energy storage devices. The plot uses logarithmic scales to display the wide range of values.

Major Assumptions

  • Battery characteristics follow the Ragone relationship:

    P = const_1 * 10^(E * const_2)

  • Specific energy range is defined by upper and lower bounds

  • Values are converted to standard units (kW/kg and Wh/kg)

Definitions

‘Specific Power’

Power output per unit mass (kW/kg)

‘Specific Energy’

Energy storage capacity per unit mass (Wh/kg)

‘Ragone Plot’
